摘要： A closed loop reciprocating fluid circuit apparatus for mechanically powered and electromechanically powered dock levelers, which may be mounted at a forward edge of a dock leveler to selectively engage the dock leveler during pivotal downward movement of a deck, is provided. The apparatus may include a header extending from a fluid chamber (e.g., a hydraulic cylinder), where the header may selectively engage the deck, within the range of dock leveler heights, including below dock level and above dock level operating positions. The hydraulic cylinder may be vertically oriented and coupled to a fluid accumulation chamber, such that vertical movement of the header in response to the deck's downward movement causes fluid displacement into the accumulation chamber. That displacement may be in a horizontally oriented fluid chamber having a piston that reacts to the fluid transfer. Alternatively, that displacement may be into a resilient fluid chamber such as a bladder housed within a suitable container, or a fluid chamber such as a fluid reservoir with a breather, for air volume compensation. The hydraulic cylinder and header may be urged to the extended position, for example by extension springs acting on a piston within the fluid accumulation chamber, or by a pull chain or latch coupled to the cylinder and the upward movement of the deck. A flow control valve, e.g., a velocity fuse or solenoid valve, is connected between the cylinder and the fluid accumulation chamber to respond to free fall of the deck. Resetting to normal operation after free fall detection may occur after load removal from the deck and by movement of the cylinder to the opposite direction or by electrical control input to the control valve.

摘要： To permit below-dock level end-loading operations and to limit accidental freefalling of a dock leveler's deck, a dock leveler includes a unique support mechanism that employs one or more safety legs with an integral or operatively connected lip deflector. The support mechanism can be selectively moved to a deck-supporting position for freefall protection or moved to a lip-deflecting position for below dock level end-loading operations. In the deck-supporting position, the safety leg prevents the deck from falling an unsafe distance. In the lip-deflecting position, the lip deflector guides the descending motion of the dock leveler's lip extension plate so that the lip, while hanging pendant, can bypass and descend below a set of lip keepers.

摘要： A dock leveler includes a vehicle-engaging pivotal lip extending from the front end of a pivotal deck, wherein the lip has one or more unique features that provide a smooth transition for forklifts traveling between the lip and a trailer bed upon which the lip is resting. The smooth transition minimizes jolting and vibration of the forklift and its driver as the forklift wheels pass over the leading edge of the lip. The special features of the lip may include one or more of the following: a curved traffic-bearing surface terminating at a sharp or blunt leading edge, a traffic-bearing surface that includes both flat and curved sections, a multifaceted traffic-bearing surface that approximates a curved surface, a rubber or plastic shock absorbing element, an articulated nose piece at the lip's leading edge, and a main lip plate that is coplanar with the deck's traffic surface (i.e., zero crown angle).

摘要： A dock leveler for a truck loading dock includes a pivotal deck that is raised by an inflatable actuator. The actuator includes a pliable upper section that when inflated has a generally vertical cylindrical shape that can provide a heavy deck with substantial columnar support. The actuator also includes a relatively rigid base that is sealingly joined to the pliable upper section such that upper section and the rigid base define an inner chamber of air. A blower for inflating the actuator can be installed inside or outside the actuator. In some embodiments, a valve system reverses the airflow so that the blower can forcibly deflate and compress the actuator up against the bottom of the deck so that the area underneath the actuator can be cleaned.

摘要： A dock leveler or dock lift deck comprises two upper plates that are connected to create a permanently visible longitudinal joint that serves as a guideline for a forklift operator. In some cases the joint may have a variable width gap that helped in squaring up the deck during manufacturing. To draw attention to the guideline, the two upper plates may each have an embossed pattern that is shifted out of registry with each other.

摘要： A wheel-activated vehicle restraint for use at a loading dock includes a wheel-blocking barrier that is selectively locked to a frame by a latching mechanism that engages an inverted gear rack. Components of the latching mechanism are arranged to prevent spreading apart upper and lower members of the frame members. The latching mechanism includes an alignment device that helps ensure that the teeth of a latching member positively engages the teeth of the gear rack, thus preventing the teeth from coming together peak-to-peak. An upper rail of the wheel restraint's frame includes a contoured leading edge that smoothly guides the lift of the wheel-blocking barrier from its stored position to its wheel-chocking position. A wheel support is used to prevent a vehicle's mud flap from getting pinched between the vehicle's wheel and a trigger assembly of the wheel restraint.

摘要： Dock leveler safety supports are disclosed herein. An example dock leveler disclosed herein includes a deck movable relative to a platform between a raised position and a lowered cross-traffic position when the dock leveler is in a working configuration. The deck to be inhibited from descending toward the lowered cross-traffic position when the dock leveler is in a service configuration. A first deck obstruction is movable relative to the deck between a secured position and an unrestrained position. The first deck obstruction in the secured position configures the dock leveler in the service configuration. The first deck obstruction in the unrestrained position configures the dock leveler in the working configuration. The first deck obstruction in the secured position to block movement of the deck toward the lowered cross-traffic position and the first deck obstruction in the unrestrained position to permit movement of the deck toward the lowered cross-traffic position. A first connector to couple the first deck obstruction to an obstruction actuator. The first connector including a rod, a sleeve to telescopically receive the rod, and a spring held in compression between the rod and the sleeve.

摘要： Dock leveler safety supports and related methods are disclosed. An example method includes raising a front end of a deck above a platform, where the front end is elongate in a lateral direction and the front end extends laterally between a first side and a second side of the deck. The method includes manually pulling a first deck obstruction in the lateral direction out from the first side so that the first deck obstruction extends out over a perimeter of the platform. The method further includes lowering the front edge of the deck until the first deck obstruction descends upon and engages the platform.
